Hello if i want to merge duplicate data, from before to after is it possible with VBA?
Thanks 🙏
 

Excel Facts

Workdays for a market open Mon, Wed, Friday?
Yes! Use "0101011" for the weekend argument in NETWORKDAYS.INTL or WORKDAY.INTL. The 7 digits start on Monday. 1 means it is a weekend.

2nd option, if you got duplicate values ( for example sunday in a2:a5 , then appear again in a10:15) then you need to try below code instead.

Another option if your intention was to merge in situ
VBA Code: 
Sub Merge_Same()
    Dim c As Range
    Application.DisplayAlerts = 0
StartMerge:
    For Each c In Sheet1.Range("B2", Cells(Rows.Count, "B").End(xlUp))
        If c = c.Offset(1) And c.Offset(1) <> "" Then
            Sheet1.Range(c, c.Offset(1)).Merge
            GoTo StartMerge
        End If
    Next c
    Application.DisplayAlerts = 1
End Sub

I note you changed the column reference from my suggested code in post #4 from column B to column D. I'm guessing that you didn't have any values in column D before running the code, and that your real intention is like you described in your original post - that is, take unmerged items in column B and merge them into column D? If that is the case, try the following code, which copies items from column B first into column D, then merges like items. If this is not what you wanted, then you'll need to give a much more detailed description of your intended outcome.
VBA Code: 
Sub Merge_Same()
    Dim c As Range
    Application.DisplayAlerts = 0
    Sheet1.Range("B2", Cells(Rows.Count, "B").End(xlUp)).Copy Sheet1.Range("D2")
StartMerge:
    For Each c In Sheet1.Range("D2", Cells(Rows.Count, "D").End(xlUp))
        If c = c.Offset(1) And c.Offset(1) <> "" Then
            Sheet1.Range(c, c.Offset(1)).Merge
            GoTo StartMerge
        End If
    Next c
    Application.DisplayAlerts = 1
End Sub
